The great âLaurel or Yannyâ debate may have been responsible for provoking online arguments and souring friendships, but a new viral audio recording threatens to dethrone it as this weekâs most mind-boggling viral mystery.

A popular explanation on the Reddit thread had to do with âpriming,â a psychological concept that holds that people perceive certain things depending on what they âprimeâ their minds with.

Others eschewed explanations of any kind, and simply worried out loud that this latest aural mystery was messing with their brains.

âOkay, brains donât make sense. Thatâs what theyâre for; making sense, and they canât even do that. Nothing makes sense anymore,â wrote one user.

âCan someone f*****g explain this to me before I have a breakdown,â said another.
